Application

4-Hydroxy Tempo is a good Inhibitor in polymerization of acrylate, methacrylate, acrylic, acrylonitrile, styrene, butadiene, and acrylonitrile.
It is use in water treatment applications.

4-Hydroxy-TEMPO (also known as TEMPOL) is a stable nitroxyl radical used as a versatile catalyst, oxidant, and polymerization inhibitor, crucial in organic synthesis for alcohol oxidation, as a spin label in research (EPR), and even studied for its antioxidant properties in biology, acting as a superoxide dismutase mimic to scavenge reactive oxygen species (ROS) in cells

Key Uses & Properties:
Catalysis: Oxidizes alcohols to aldehydes/ketones, often with co-oxidants like bleach (hypochlorite).
Polymerization Control: Acts as an efficient inhibitor for radical polymerization (e.g., acrylates, styrene).
Biomedical Research: Mimics superoxide dismutase (SOD), scavenging ROS and protecting cells from oxidative damage, relevant in understanding diseases like obesity.
Spin Label: Used in Electron Paramagnetic Resonance (EPR) spectroscopy to study biological molecules and polymers.
Chemical Synthesis: Starting material for other TEMPO derivatives and polymer systems.
